Secure Medical Image Storage Using Cross-Chain Technology
Chunmei Liao, Hong Su, Xi Wu, Jing Peng, Ting Wang, Zheng Zhou · 2023
The storage and management of medical images present significant challenges due to their unique characteristics that require careful consideration of security and privacy. Traditional centralized server-based approaches to medical image storage and management are vulnerable to server crashes, which can result in data exposure risks. Blockchain technology can enhance the security of medical image data, but it may negatively affect data throughput. To address this issue, this paper proposes a blockchain data storage system that leverages image classification and deep learning-based pre-processing to improve the efficiency of blockchain storage. By pre-screening the medical data to be stored, the proposed approach can mitigate the negative impact of blockchain technology on data throughput. The verification results show that the proposed method can increase the storage capacity of blockchain and improve data throughput by distributing medical image data across multiple blockchains.
